JUSTUS C. GOOSMANN,

-OF PEORIA, ILLINOIS.

CONDENSER.

Application filed .Tune 4,

To all whom 'it 'may concern Be it known that I/,lfus'rus C. GoosMANN, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Y Illinois, have invented certain new and use.- ful Improvements in Condensers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to improvements in coolers or condenser-s, having especial reference to an apparatus of this class employed in the process of condensing gases as used in refrigerating systems.

Ordinarily, the construction of a condenser for this purpose is such that the gas to be liquefied is introduced in suoli a way as to greatly disturb the portion thereof undergoing liquefaction, nearly the whole gas being kept in violent agitation with the result that quiet descent of the gas through and over the cooling surfaces cannot take place to best obtain rapid cooling and condensing.

In view of the disadvantages of many of the older types, therefore, it is my purpose and object to furnish a condenser so arranged that the gas to be condensed may be introduced thereto in such a way that it will be permitted to slowly settle down through and over the cooling surfaces with the least possible amount of agitation whereby to obtain quicker cooling, as well as to prevent unliquefied gas passing out with the liquelied portion.

To the end that my invention may be understood, the appended drawing has been furnished showing the mannerof constructing the condenser, though it is to be understood that changes may be made therein such as may be considered properly falling within the invention and the accompanying claim.

Figure l is a vertical section of a condenser in one of the forms in which I prefer to construct it.

Figs. 2 and 3 are transverse sections of the same.

Fig. 4 is a vertical section of a portion of a modified form of the condenser structure.

1 indicates a casing of the desired diameter and length, threaded at its ends and adapted at its lower end to screw into a base portion 2 provided with a suitable stand or 1920. Serial No. 386,592.

support 3, a portion only of which is shown, while the upper end receives a cap or headportion 4, all fitted in a gas-tight manner.

One or more pipe coils 5, 6 are erected within the casing, their lower ends terminating in a manifold 7, for example, with G0 which connects in any suitable manner a conduit 8 for water. he upper ends of said coils are likewise connected into a similar manifold 9 connecting with an overflow pipe 10, the cooling medium, usually water, entering the coils 5 and 6 by wayof the lower manifold 7 described.

ll. is a conduit in the base-portion 2 for entrance of the gas to be liquefied, l2 designating a stand-pipe connected into said conduit and terminating at its top in an open end within the upper end of the cavity 'of the said casing l, the character 13 indicating a second conduit in the base -2 for the discharge of the liquefied gas. Y

In Fig. 4 the same reference characters are employed in designating like parts. In this ligure, however, the stand-pipe 12 is replaced by a pipe 14, entering through the top 4, for example, for the entrance of the gas, the same being furnished with a bend or goose-neck whereby its open end will be made to discharge the gas upwardly into the top of the cavity as before.

The water enters from below, flowing upwardly through the pipe coils and out at the top. The gas may iow fromA any desired direction so long as the discharge end of the pipe or conduit conveying it is directed into the upper end of the cavity within the casing l toward the head 4, or at least in such direction that the gas discharge shall not be caused to be deflected downward toward the liquefying portion in the bottom of said cavity.

Now, since the gas is directed toward the top 4 the agitation thereof will be confinedV to the upper portion of the cavity and therefore impart but little turbulency.

Thus as the gas tends to more and more come to rest farther down and meets the cooling coils, its cooling and precipitation is assured and this action will be much more rapid than in those types of condensers where the gas is directed downwardly toward and into the cooler portions which, as it may be readily understood, will be so kept in agitation as to often cause portions of unliqueied gases to be carried over with the liquid portion, besides which the cooling action is naturally much hindered.

l/Vhile I have shown two ways in which the gas conduit. may enter the cavity having the coils 5 and 6,'and there may be others, the form shown in Fig. l is to be preferred Lt'or the reason that the gas in entering at the bottom. is subjected to the cooling action of the cooler water in the bottom of the coils and also to that of liquefied gas in the bottom of the cavity, tending thereby to influence such entering` gas in the direction of liquefaction before being released, to the endk that it may be inclined to be less turbulent upon issuing into the cavity.

The gas, upon liquefaction, will form kglobules or drops which in descending through the unliqueiied O'as will tend to cool those portions immediately surrounding said globules or drops, liquetying such portions and drawing them into the same, the

`size of each globule increasing, thereby more readily condensing and liquefying the gas volume contained within the cavity.

The gas as delivered from the pipe or conduit 12in condensing flows counter to the direction of flow of water in the coils. That vis to say, the lower portions of the coils are coldest since the flow of water is upward, and the gas being warmest at the top in descending will meet a constantly decreasing coil temperature, resulting in a faster liquefaction. This counter-f1ow of the gas and cooling water is believed to be new in a condenser for the purposes named.

I claim 2- Ina condenser, the combination of a vertically disposed shell adapted to contain the condensed medium, a bottom and a top closii'ig said shell, a plurality of coils arranged within the shell and extending from end to end thereof, headers connected to the upper and lower ends, respectively, of said coils, means for supplying cooling fluid to the lower header through said bottom, means for discharging said fluid from the upper header through said top, a pipe for delivering the medium to be cooled into said shell, the delivery end of said pipe being disposed in proximity to said top and directed toward the top to discharge said inediuin upwardly into the upper end of said shell, so that said medium may flow downwardly over and around said coils and be subjected to the cooling action thereof with a minimum or agitation, and a passage for conducting the condensed medium from said shell through said bottom.

ln testimony whereof I affix my signature .in presence of two witnesses.
